The Ribera del Morrazo Protected Geographical Indication is made up of 8 municipalities, Pontevedra, Poio, Vilaboa, Bueu, Cangas, Moaña, Marín and Redondela that, due to their climatic, orographic and geological characteristics, make unique wines in this territory.
Within the enormous climatic heterogeneity that Galicia presents as a consequence of the direct marine influence and the relief of the territory, the protected zone presents a clearly determined climate that we can classify as oceanic-humid. Likewise, almost all of the area devoted to the cultivation of the wine is below 150 m. n. m., located in the coastal area (Peninsula del Morrazo and bottoms of the Rías de Pontevedra and Vigo), we have wings, with gentle slopes and orientations protected by the relays of the Morrazo ridge, the Sierra del Castrove to the north, the elevations towards Sierra del Suído in the east and the Sierra del Gallinero in the south, which exert an important barrier effect on the penetration of ocean winds, a fact that represents the ideal conditions for an area of great agricultural productivity.
In the agricultural region in which the wines of the protected geographical indication Ribeira del Morrazo are produced, it enjoys about 2,100 hours of sunshine a year and mild temperatures with a reduced thermal amplitude in the vegetative period, between 7.3 and 25.7 º C, with high temperatures in the winter period (above 9º of average temperature in the month of January), with a practical absence of frost and with precipitations that are between 1,300 and 1,800 mm, to which it must be united the orientation of the mountain ranges mentioned above that produces a summer weakening of the precipitations, that when combined with relatively high temperatures at the same time induce high values of evapotranspiration (between 600 and 800 mm in the year) and consequently, an accused Mediterranean influence in this period, with average temperatures around 18 º C, which clearly benefits the cultivation of the vine.
Most soils are moderately acidic, permeable, with low water retention capacity and with little organic matter content in their most superficial layer. They are, in their majority, old soils, with sufficient depth and well-nurtured by insolation, which makes them well-suited for cultivation.
